为了解组合墙体-楼盖梁规程连接体系(CS)和新型连接体系(NS)的力学性能,采用ANSYS软件建立了有限元模型,并对不同轴压比下的CS体系、不同连接角钢厚度下的NS体系进行了低周往复加载模拟,得到了两类体系的骨架曲线、承载力特征值等结果。结果表明:轴压比增加,CS体系承载力降低,且降幅增大,延性系数减小;连接角钢厚度在0.8~2倍墙架柱构件厚度范围内时,角钢厚度增加,NS体系承载力提高;其中角钢厚度为1.2~1.5倍的墙架柱构件厚度时,体系延性系数有最大值;当角钢厚度超过2倍墙架柱构件厚度后,体系承载力变化不大。
In order to understand the mechanical properties of the combined wall-floor girder procedure connection system (CS) and the new connection system (NS), a finite element model was established using ANSYS software, and CS systems with different axial pressure ratios and different connection angles were The thickness of the NS system was simulated by low-cycle reciprocating loading, and the results of the skeleton curves and bearing capacity characteristics of the two types of systems were obtained. The results show that the axial compression ratio increases, the bearing capacity of the CS system decreases, and the decreasing amplitude increases, and the ductility coefficient decreases. When the thickness of the connecting angle steel is within 0.8~2 times the thickness of the wall frame column member, the thickness of the angle steel increases, and the bearing capacity of the NS system increases. The ductility coefficient of the system has a maximum value when the thickness of the angle frame steel is 1.2~1.5 times the thickness of the wall frame member; when the thickness of the angle steel exceeds the thickness of the wall frame member of the double wall frame, the bearing capacity of the system does not change much.
